Hello! Firstly, thank you so much for making these videos! Secondly, I was wondering what the criteria is for choosing your initial x and y variable. If I want to predict the number of tea gallons that will likely be sold, should I use the number of people who walked in the store on the same day last year? That does not seem to be correct to me, but I'm not sure what else to predict such a thing off of. Whether or not you answer the question, I appreciate your time!

1. It could be you need to increase the width of your excel column. 2. You may need to reduce the number of decimal points. You can attach your spreadsheet or a photograph of your work on messages on MyBookSucks FaceBook fan page (see link in the description of this video). I will look at it and see if can't figure out what you are doing wrong.

Ok thanks. Your videos are nice and understandable. I want to ask if slopes of two or more than two regression lines (b) is possible to compare by t-test or Ancova.

Just to make things easier - if you want to keep some cell constant in a formula in excel, you don't have to put there mechanically $ signs, just hit F4 key and the computer puts the signs there for you ;-)
